现行规范推荐的沥青路面路表弯沉季节影响系数已不适应如今公路建设快速发展的施工技术水平,需要通过研究路基路面各结构层的模量等参数变化对路表弯沉产生的影响。该文结合相关规范,提出路表弯沉季节影响系数的表达式。在公路弯沉检测过程中要重点考虑路基回弹模量变化对路表弯沉的影响,在对大量试验路段检测数据进行分析的基础上,通过公式计算分别提出不同地区不同条件下的路表弯沉季节影响系数,使其更具有区域性。
The current normative recommended asphalt pavement season deflection season influence coefficient has not adapted to the rapid development of highway construction technology level, the need to study the impact of road surface deflection by changing the modulus and other parameters of the subgrade pavement structure. In this paper, the expressions of season influence coefficient of road surface deflection are proposed in combination with relevant norms. In the process of highway deflection detection, the influence of the subgrade resilience modulus on the deflection of the road surface should be considered in detail. Based on the analysis of the test data of a large number of test sections, the formula of the road surface table under different conditions in different regions Deflection season affect the coefficient, making it more regional.
